Problems solved by technology

This method has certain limitations. On the one hand, the rock mass is directly exposed in the air, and the slope stability is affected by the direct erosion of rainwater; on the other hand, it is difficult for plants to grow on the upper part of the concrete lattice beam, and the landscape effect is poor.

Embodiment 1

[0047] see figure 1 As shown, the present embodiment provides a kind of ecological protection structure of broken rocky steep slope, hereinafter referred to as slope protection, including seed soil layer 1, barbed wire 2 layers, nutrient soil base 3, and concrete lattice that are arranged on the slope from top to bottom successively. girders 4, such as image 3 As shown, the grid of the concrete lattice beam 4 is built with a planting bag 5 under the nutrient soil base 3 .

[0048] The uppermost seed soil layer 1 can provide early nutrients for plant growth, wherein the thickness of the seed soil layer 1 can be 20-30 mm.

[0049]The root system of the plant extends to the nutrient soil base 3 to further strengthen the strength and integrity of the nutrient soil base 3, wherein the thickness of the nutrient soil base 3 can be 80-90mm. The plant root system guides the infiltration of rainwater, increasing the water flow space to ensure the water needed by plants.

Embodiment 2

[0059] The present embodiment provides a construction method for the ecological protection structure of the broken rock steep slope described in Embodiment 1, specifically comprising the following steps:

[0060] S01. Cleaning and leveling the slope surface, mainly cleaning and leveling the slope surface for subsequent construction.

[0061] S02. Stakeout planning: according to the on-site stakeout of the construction drawings, determine the construction positions of the anchor rod 7 and the lattice beam 4.

[0062] S03, installation of anchor rod 7: according to the anchor rod 7 determined in step S02, locate, drill, install the anchor rod and fix it by grouting;

[0063] Wherein the construction method of anchor rod 7 specifically comprises the steps:

[0064] S031. Carry out dry drilling on the slope to drill holes, and use high-pressure air to clean (0.4MPa) to ensure good consolidation of mortar and hole walls;

[0065] S032. Filling cement mortar, the grouting pipe and...

Embodiment 3

[0080] In the step S05 of Embodiment 1 and Embodiment 2, the lattice beam 4 that needs to be formed and solidified is a porous structure, so this embodiment provides a concrete manufacturing method for forming a porous lattice beam 4, which specifically includes the following steps:

[0081] S051: In parts by weight, prepare the following raw materials: 10-13 parts of water, 34-37 parts of cement, 135-145 parts of gravel aggregate, 0.6-1.1 parts of polycarboxylate superplasticizer, 1.4- 2 parts of strengthening agent, 2-2.5 parts of mineral admixture.

[0082] In step S051:

[0083] Mineral admixture can use silica fume;

[0084] The cement is made of ordinary Portland cement with strength grade 42.5; the technical performance index of the cement is qualified, and the stability is qualified;

[0085] The crushed stone aggregate particle size is 5-10mm, the gradation is uniform, the apparent density is 2500-2800kg / m3, the close packing density is 1400-1500kg / m3, and does not ...

Abstract

The invention relates to the technical field of a side slope protection structure, and in particular relates to an ecological protection structure for a broken rock steep slope and a construction method thereof. The ecological protection structure for the broken rock steep slope comprises a seed soil layer, a steel wire net layer, a nutrient soil base layer and a concrete lattice beam which are arranged on a slope surface from top to bottom in sequence, wherein vegetative bags positioned under the nutrient soil base layer are stacked in lattices of the concrete lattice beam; the lower part ofthe lattice beam is buried in the slope surface; and an ear wall is arranged at the lower part of the lattice beam. The ecological protection structure can effectively prevent landslide and can also ensure the normal growth of vegetation, thus playing an excellent protective effect on a side slope.

Description

technical field [0001] The invention relates to the technical field of slope protection structures, in particular to an ecological protection structure for broken rock steep slopes and a construction method thereof. Background technique [0002] In order to alleviate the damage to the natural environment caused by the rapid economic development in recent years and to meet the people's needs for a better environment, the research and promotion of restoration and greening technology has become a current hot spot. The mountain slope is the exposed surface of the mountain formed by artificial excavation or natural external forces, which widely exists in cities and along highways. Vegetation and other coverings on the slope surface are often destroyed by excavation, causing serious impacts: on the one hand, it is incompatible with the surrounding environment, and on the other hand, it is easy to cause disasters such as rock collapse and landslides. There are many types of tradit...
